Title: Laminated heat exchanger
Inventor: SEKI MASAHIRO
IPC: F28D9/00
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To enhance a heat exchanging efficiency by prolonging a residence time of an exhaust gas and the air passing a heat exchanger. SOLUTION: The heat exchanger 1 is constituted by alternately laminating heat transfer plates 4 having recesses 2 and protrusions 3 alternately formed and flat plate-like partition plates 5. Rising parts 12 for partitioning the recesses 2 and the protrusions 3 are vertically symmetrical waveform curves to form channels 8A, 8B having alternately continuously curved wide parts 13 and narrow parts 14. Conical barrier walls 15, 16 are formed at a central part of the wide parts 13. Thus, an exhaust gas and the air passing the channels 8A, 8B collide with the walls 15, 16 to be branched so as to be detoured, and hence residence times of the gas and the air in the exchanger 1 are prolonged to enhance a heat exchanging efficiency.

Title: Stream multiplex device, stream multiplex method and storage medium
Inventor: UI SHUNJI
IPC: G11B20/10
Filed: 1995-06-08
Abstract: PURPOSE: To shorten the reproduction return time at the time of a random access by performing the specifying of packets in order of the last packet so that multiplex positions are arranged narrowly at positions nearest for decoding start times of data units from the rear. CONSTITUTION: Frames 1∼3 in an audio stream are divided into packet data AP1∼AP5 having a specific length. In the case the packet to be arranged next is AP4, the packet AP4 is arranged at the last arrangeable position 15 and the multiplex control information of the packet are recorded in a control information recording part. Since the packet AP3 is all the data of the frame 2, the packet AP3 is arranged at the last possible position 14. Moreover, similarly, the packet AP2 is arranged at the last possible position 5. Thus, the reproduction return time at the time of the random access is shortened by specifying the arrangement of the voice stream so that multiplex positions are arranged narrowly at positions nearest for the decoding start times of data units from the rear.

Title: Deflector for thin picture tube
Inventor: NAKAMURA YUKIO
IPC: H01J29/76
Filed: 1984-07-11
Abstract: PURPOSE:To enable a ferrite core having a conventional shape to be used and enable the deflection center to be shifted toward the front by making the deflection center of the deflection coil adjacent to the funnel section of a thin picture tube. CONSTITUTION:A horizontally deflecting coil wound in a saddle-like form has a turned-up section 11a in its front head. The inner circumference surface of the turned-up section 11a forms a horizontal ellipse which conforms with the shape of a funnel section 2. The turned-up section 11a protrudes from the end of a ferrite core 10 by a distance (D) which is 20-30% of the total length of the deflector. Therefore, it is possible to set the deflection center of the horizontal deflection magnetic field at a point apart from the neck section toward the funnel section 2. Consequently, it is possible to use a ferrite core having a conventional shape and to shift the deflection center toward the front.

Title: Scanning method of copying machine
Inventor: ASAKURA KOUICHI
IPC: G03G15/30
Filed: 1978-11-20
Abstract: PURPOSE:To prevent occurrence of excess image, etc. on the transfer paper, by stopping the light source or original platen for a certain period, without returning immediately after finishing scanning, or returning after permitting to run in the going direction by inertia. CONSTITUTION:When the scanning of the original is over, a going stroke relay contact RA1 becomes OFF, and a going stroke electromagnetic clutch MC1 is set to OFF, while a returning stroke relay contact RA2 becomes ON at the same time. At this time, a capacitor C1 is inserted between the base and emitter of a transistor Tr1, and this Tr1 is constituted to be made to conduct after complete charging of C1 so that an electromagnetic clutch MC2 in the returning direction may be actuated. That is, this specified action delay time t is determined by the time constants C1.R1 in the timer circuit. In this course, the light source or original platen runs in the going direction by inertia, and then returns to the scanning start point when the electromagnetic clutch MC2 becomes ON later. Therefore, when the delay time t is set to a duration necessary for eliminating the image on the photoreceptor, the effect of the image on the photoreceptor may be removed.
